LBUD provides potable water, recycled water, and sewer collection services to a
population of approximately 470,000 within a 52-square mile area in the City of Long
Beach.
The LBUD meets its potable water demand through a combination of purchased treated
surface water from Metropolitan Water District of Southern California (MWD) and local
groundwater treated at the Groundwater Treatment Plant (GWTP) using a conventional
treatment process. The source of the raw water for the GWTP is currently from 24 active wells located
throughout the City of Long Beach (see the attached Appendix G - Well Locations
and Collection Pipeline Map). The current combined capacity of the wells is
approximately 25 MGD. LBUD plans to drill additional water wells in both the Central and West Coast
adjudicated groundwater basins. The goal is to shift supply portfolio to increase
pumping capacity and cycle the wells in operation as needed. Existing well collection
pipeline reliability is critical to accommodate the expected increase in local groundwater
production. LBUD's existing well collection system primarily includes the western area, eastern area
and southern area. In 2017, LBUD performed a well siting and well collection system
study. The study raised the concern in some areas of the collection system. One of
main concern is the western area. The area of concern in western area is composed of
20-inch, 24-inch and 30-inch CI pipes and serve wells located in Jackson Park in North
Long Beach, Development 5, 9 and North Long Beach 12 near Long Beach Airport (see
the attached Appendix F - Project Location Map). Due to unknown condition of the
collection system, LBUD is concerned that increase in operational pressures in the
collection system due to additional well flow loading or changes in system operations
may result in leaks or pipe breaks, especially in the older areas of the system. LBUD has performed opportunistic CCTV/Condition Assessment of portion of the
western collection pipelines. Results of the assessment is available upon request. The Project consists of engineering design services to determine constructability and
cost benefit analysis of utilizing various pipeline improvement methods. Consultant will
recommend and assist LBUD in the selection of construction improvement method. The
engineering design services will need to consider replacement of other appurtenances
such as laterals, blow-offs, and valves. Once the improvement method is selected, the Consultant shall prepare detailed design
drawings, specifications, bid support and evaluations, and recommendation of
contractor bid award. The Consultant is also required to include Engineering Support
Services During Construction in the proposals which are listed in Task B as optional
work. Please contact Myung Chun at (562) 570-2357 or Myung.Chun@lbutilities.org if you have any
questions regarding this project. The LBUD reserves the right to reject any or all proposals. The LBUD will select the Consultant,
which appears most likely to provide the services under the conditions that would be in the best
interest of the LBUD. The method of Contractor Selection has not been Determined at this time.
